Description

Technical Field

[0001] The utility model relates to the technical field of beauty instruments, in particular to a skin care device. Background Art

[0002] In the development process of beauty devices, cold therapy mode has gradually been introduced as a new beauty care method. When implementing cold therapy mode, existing beauty devices usually use a relatively simple and direct physical cooling method.

[0003] The principle of this physical cooling is often to directly reduce the temperature of the part in contact with the skin with the help of certain cooling elements, such as semiconductor refrigerators or liquid nitrogen. However, the cold therapy effect of this method that relies on temperature reduction is often poor. Specifically, different layers have different sensitivities and reactions to temperature changes. Simple cold therapy modes do not fully consider the physiological characteristics of the skin and its complex reaction mechanism to cold stimuli. By simply reducing the surface temperature, the cold stimulus cannot be effectively transmitted to the deep skin tissue, and thus the cold therapy cannot fully play its due role. Therefore, the cold therapy effect is poor. Utility Model Content

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0043] The present invention provides a skin care device 100, which is mainly used for caring for skin. The skin may be facial skin, hand skin, leg skin, abdominal skin, or skin on other parts of the human body.

[0044] See also Figure 1 and Figure 2 The skin care device 100 provided in the first embodiment of the present application includes: a cooling module 101 and an irradiation module 102 .

[0045] The cooling module 101 includes a cooling element 1011. This cooling element 1011 serves as the cooling unit for the skin care device 100 to provide cold therapy, outputting cooling energy during the cold therapy process. When DC current passes through this cooling element 1011, it absorbs heat at its joints, thereby cooling the surrounding environment and generating cooling energy. This cooling element 1011 can be a thermocouple composed of at least two different semiconductor materials.

[0046] It should be noted that when current passes through cooling element 1011, electrons move between at least two different semiconductor materials within cooling element 1011. Due to differences in the electronic band structures of these materials, the electrons absorb or release energy during the transfer from one material to the other. At the cooling end, the electrons absorb heat, lowering the temperature. The cooling energy is then transferred to the contacting object through heat conduction, such as the contact surface of a skin care device with the skin.

[0047] Please continue reading Figures 3 to 5 The illumination module 102 includes a blue light emitting module 1021 and / or a green light emitting module 1022. The blue light emitting module 1021 is used to output a blue light signal of a preset wavelength, and the green light emitting module is used to output a green light signal of a preset wavelength.

[0048] In this embodiment, the illumination module 102 may include at least one light emitting module, and the at least one light emitting module may include at least one of a blue light emitting module 1021 and a green light emitting module 1022. The blue light emitting module 1021 generally uses a blue light emitting diode (LED) of a specific wavelength as the main light source, and the blue light emitting module 1021 may also include a lens, a reflector, a filter, etc. The lens is used to focus and diffuse blue light to meet different application requirements. The reflector can reflect blue light in a specific direction to improve the utilization rate of light. The filter can filter out unnecessary wavelengths and allow blue light of a specific wavelength to pass through to improve the purity and quality of the blue light.

[0049] Please continue reading Figure 4 and Figure 5 The blue light emitting module 1021 and the green light emitting module 1022 may both include a light emitting element 1023 , which may be a laser diode. The light emitting element 1023 may serve as the light source of the blue light emitting module 1021 and the green light emitting module 1022 , respectively.

[0050] The blue light signal and / or green light signal output by the blue light emitting module 1021 and the green light emitting module 1022 in the irradiation module 102 are transmitted to the nursing area via the cooling module 101 to provide nursing care for the nursing area.

[0051] Please continue reading Figure 1 and Figure 2 Refrigeration module 101 can quickly lower the temperature of the treatment area. Low temperatures can soothe the skin. For example, after skin irritation, low temperatures can constrict blood vessels, reduce inflammation, and alleviate redness, swelling, and pain. For sensitive skin or those experiencing a sensitive period after a beauty treatment, the cooling effect of refrigeration module 101 can help the skin quickly return to a stable state and alleviate discomfort.

[0052] Blue light signals typically have wavelengths between 455 and 475 nanometers. In beauty care, specific wavelengths of blue light have antibacterial and anti-inflammatory properties and can accelerate cell metabolism. Green light signals typically have wavelengths between 500 and 520 nanometers. Green light has a soothing and calming effect in skin care. For sensitive skin, green light can alleviate symptoms such as redness and itching. This, in turn, regulates the skin's immune system, strengthens its resistance, and reduces the impact of external stimuli on the skin.

[0053] When the blue light and / or green light signals are transmitted to the care area through the cooling module 101, since both act on the same skin at the same time, the bactericidal, anti-inflammatory, soothing and accelerated cell metabolism of the blue light, or the soothing and calming effect of the green light can enhance the calming effect of the cooling module on the skin, while accelerating cell metabolism, allowing new cells to reach the skin surface faster and then soothe and calm, achieving a synergistic care effect on the skin.

[0054] Please continue reading Figure 1 The refrigeration module 101 further includes a light-transmitting cooling component 1012 .

[0055] The light-transmitting cooling element 1012 has good light-transmitting capability, which allows the blue light signal and the green light signal respectively emitted from the blue light emitting module 1021 and / or the green light emitting module 1022 to pass through the element and reach the nursing area.

[0056] It should be noted that the light-transmitting cooling member 1012 needs to have both light transmittance and cooling conductivity.

[0057] Specifically, different materials have different transmittances for light of different wavelengths. When selecting the material for the light-transmitting cooling element 1012, compatibility with the specific blue and green light wavelengths used by the beauty device needs to be considered. For example, optical glass or transparent plastic has a high transmittance for the blue and green light signals of the preset wavelengths emitted by the blue light emission module 1021 and / or the green light emission module 1022, thereby minimizing loss of the optical signals during transmission.

[0058] Furthermore, the light-transmitting cooling element 1012 must possess excellent cooling performance. The cooling energy generated by the refrigeration module must be effectively transferred to the treatment area through this component to achieve the desired cooling effect. The cooling performance of the light-transmitting cooling element 1012 depends primarily on the thermal conductivity of the material; higher thermal conductivity results in faster cooling energy transfer.

[0059] Please continue reading Figure 1 The light-transmitting cooling element 1012 is located on one side of the refrigeration element, and the cooling energy generated by the refrigeration element 1011 is transferred to the nursing area through the light-transmitting cooling element 1012 .

[0060] The light-transmitting cooling element 1012 can be directly attached to the surface of the cooling element to minimize thermal resistance and ensure rapid transfer of cooling energy. Alternatively, the two can be connected via a specific heat-conducting medium to optimize heat transfer efficiency while also ensuring structural stability and maintainability.

[0061] The cooling element 1011 may be a component in the skin care device that generates cooling energy. For example, the cooling element 1011 may be a semiconductor refrigeration chip that utilizes the Peltier effect to generate cooling energy by switching on and off current or by compressing a refrigerant to reduce temperature.

[0062] After the refrigeration element 1011 outputs cooling energy, the cooling energy is transferred to the light-transmitting cooling element 1012 , and the light-transmitting cooling element 1012 can transfer the cooling energy to the care area.

[0063] Please continue reading Figure 1 The blue light signal output by the blue light emission module 1021 is transmitted to the nursing area via the light-transmitting cooling member 1012; and / or

[0064] The green light signal output by the green light emitting module 1022 is transmitted to the nursing area through the transparent cooling member 1012 .

[0065] While the cooling element 1011 generates cooling energy, the blue light emitting module 1021 and / or the green light emitting module 1022 may output corresponding blue light signals and / or green light signals.

[0066] The simultaneous output of cooling energy and light signals can exert a synergistic effect and enhance the care effect on the care area. For example, cooling energy can constrict skin blood vessels and reduce inflammatory reactions. Combined with the bactericidal effect of blue light, it can more effectively care for skin problems such as acne. The soothing effect of green light can also be enhanced in a cooling environment, providing better care for sensitive skin. At the same time, since blue light and / or green light also generate a certain amount of heat, transmitting blue light and / or green light to the care area through the transparent cooling element is also beneficial for the cooling element to further reduce the heat of blue light and / or green light, thereby reducing the heat reaching the skin and playing the role of cell cold therapy.

[0067] Please continue reading Figures 3 to 5 The skin care device 100 further includes an annular reflector 105, which is disposed between the blue light emitting module 1021 or the green light emitting module 1022 and the light-transmitting cooling element 1012. The annular reflector 105 encloses a hollow inner hole, through which light emitted by the light-emitting elements in the blue light emitting module 1021 or the green light emitting module 1022 passes, irradiating the light-transmitting cooling element 1012 and transmitting the light to the treatment area.

[0068] The annular reflector 105 is ring-shaped. First, the ring can surround one side of the blue light emitting module 1021 or the green light emitting module 1022, providing a continuous and uniform reflective surface for light. Second, the hollow portion of the ring allows light to pass through, forming a specific optical path, minimizing light loss and ensuring that light accurately reaches the target area.

[0069] Light passes through the hollow inner hole and hits the translucent cooling element, which then transmits it to the treatment area. During this process, the hollow inner hole acts as a bridge connecting the light-emitting module and the treatment area. This ensures that the light is not blocked or scattered by other objects during transmission, allowing it to efficiently reach the treatment area and achieve the desired skin care effect.

[0070] As an embodiment, the light-transmitting cooling member 1012 is sapphire.

[0071] It's important to note that sapphire is extremely transparent and has a very high transmittance for visible light, especially in the wavelengths corresponding to blue and green light signals. This allows the signals from the blue and green light emission modules to pass through the sapphire light-transmitting cooling element with virtually no loss, ensuring the effectiveness of phototherapy. Whether it's the specific wavelength of blue light used for sterilization and anti-inflammation, or the soothing green light, both reach the treatment area with maximum intensity, delivering their intended therapeutic benefits.

[0072] Furthermore, sapphire's high thermal conductivity allows it to quickly and efficiently conduct the cooling energy generated by the cooling element. When the cooling element is operating, the sapphire acts as a light-transmitting cooling element, rapidly transferring cooling energy to the treatment area, achieving highly effective cold therapy. This rapid thermal conductivity ensures rapid cooling of the treatment area, constricting blood vessels, reducing inflammation, and providing a comfortable skin environment.

[0073] Sapphire's excellent light transmittance and cooling properties allow for the perfect combination of light therapy and cold therapy, significantly enhancing the effectiveness of skin care devices. For skin conditions like acne and blackheads, the antiseptic and anti-inflammatory effects of blue light combined with the cooling and vasoconstricting effects of cold therapy synergize to more quickly alleviate symptoms. For sensitive skin, the soothing and calming effects of green light combined with the comforting care of cold therapy can further alleviate skin discomfort.

[0074] At the same time, the uniform light transmittance and cooling performance of sapphire can ensure that every part of the care area is adequately cared for, avoiding the problem of poor local care effects.

[0075] Please continue reading Figure 1 and Figures 3 to 5 The light-transmitting cooling member 1012 includes a first end face 1012a facing the skin and a second end face 1012b opposite to the first end face. The first end face of the light-transmitting skin-contacting member is in contact with the skin for caring for the care area.

[0076] The blue light emitting module 1021 and / or the green light emitting module 1022 is disposed on a side opposite to the second end surface 1012 b .

[0077] The light-transmitting cooling element 1012 has two clearly distinguished end faces, namely a first end face 1012a facing the skin and a second end face 1012b facing away from the skin, which helps to clarify its functional direction during use. The first end face 1012a directly contacts the skin of the care area and undertakes the key task of delivering light therapy and cold therapy to the skin. The second end face 1012b is usually connected to internal components such as the cooling element and the light emission module, and can be used to receive cooling energy from the cooling element 1011 and optical signals from the blue light emission module 1021 and / or the green light emission module 1022, and transmit the cooling energy and optical signals to the first end face 1012a.

[0078] The close contact of the first end surface 1012a with the skin is crucial for achieving effective treatment. This close contact ensures that cooling energy and optical signals are directly delivered to the treated area, minimizing energy loss and signal scattering. When the first end surface is in close contact with the skin, the cooling energy generated by the cooling element is rapidly transferred to the skin surface, lowering the skin temperature and achieving a cold therapy effect.

[0079] At the same time, the blue light signals and / or green light signals emitted by the blue light emitting module 1021 and / or the green light emitting module 1022 can be efficiently transmitted to the skin through the first end surface 1012a of the transparent cooling member 1012, thereby exerting their specific skin care effects. For example, blue light can kill bacteria and reduce inflammation, while green light can soothe and calm the skin, thereby providing targeted phototherapy for the treatment area.

[0080] Please continue reading Figure 2 In some embodiments, the skin care device 100 further includes a control module 103, which is electrically connected to the cooling module 101 and the irradiation module 102, and is used to output control instructions for controlling the cooling module 101 and the irradiation module 102 to perform skin care. After receiving the control instructions, the cooling module 101 and the irradiation module 102 start working to care for the care area.

[0081] As the core control unit of the skin care device 100, the control module 103 plays a crucial coordinating role. It is electrically connected to the cooling module 101 and the irradiation module 102, enabling precise control of the operating status of these two key modules. By outputting specific control commands, the control module determines when the cooling and irradiation modules should activate, at what intensity, and for how long.

[0082] For example, during skin care, the control module can activate the cooling module in a timely manner based on the user's needs and skin condition, generating cooling energy to reduce the temperature of the treatment area and alleviate skin inflammation, redness, and swelling. At the same time, the control module can also control the illumination module to output blue or green light signals of specific wavelengths to achieve different treatment effects, such as sterilization and anti-inflammatory, soothing and calming.

[0083] Please continue reading Figure 2 The skin care device 100 also includes a mode selection module 104, which is used to select the working mode of the skin care device 100, wherein the working mode of the skin care device 100 includes a cold therapy mode, and the mode selection module is electrically connected to the control module.

[0084] The control module 103 is configured to control the cooling module and the irradiation module to operate when receiving an input signal from the mode selection module selecting the cold therapy mode.

[0085] The control module 103 is electrically connected to the mode selection module 104 and is capable of receiving real-time input signals from the mode selection module 104. When the user selects the cold therapy mode through the mode selection module 104, the control module 103 immediately responds to this input signal and controls the operation of the cooling module and the irradiation module according to the preset parameters of the cold therapy mode.

[0086] Specifically, the control module 103 adjusts the operating parameters of each module based on the requirements of the cold therapy mode to ensure stable and effective operation of the device in cold therapy mode. For example, the control module 103 can increase the power of the cooling module to quickly reduce the temperature of the treatment area; at the same time, it can adjust the operating state of the irradiation module to match the cold therapy mode.

[0087] Please continue reading Figure 1 , the mode selection module 104 includes at least one mode selection control component 1041, and the at least one mode selection control component 1041 is located outside the skin care device;

[0088] When the control module 103 receives the input signal of the cold therapy mode from the mode selection control component 1041, it controls the cooling module 101 and the irradiation module 102 to perform skin care at the same time or with an interval less than a preset time.

[0089] At least one mode selection control component 1041 within the mode selection module 104 is a key component in user interaction with the skin care device. These controls can take various forms, such as physical buttons, knobs, and touch-sensitive areas, allowing users to easily select different operating modes to meet their personalized skin care needs.

[0090] The location of the mode selection controls 1041 on the outside of the skin care device enhances user convenience. Users can access and operate these controls directly from the device's surface, without having to open the device or perform complex operations. This layout makes the device more intuitive and easy to use, enhancing the user experience.

[0091] The control module 103 is electrically connected to the mode selection control component 1041 and is capable of receiving real-time input signals from these components. When the user operates the mode selection control component to select the cold therapy mode, the control module immediately senses this signal and begins processing accordingly. This rapid response capability is key to ensuring that the device can meet user needs in a timely manner. Based on the type and content of the input signal, the control module identifies the user-selected cold therapy mode and prepares to control the cooling module and irradiation module.

[0092] The mode selection module 104 includes at least one mode selection control component 1041, and the at least one mode selection control component is located on the outside of the skin care device;

[0093] When the control module 103 receives the input signal of the cold therapy mode from the mode selection control component 1041, it controls the cooling module 101 and the irradiation module 102 to perform skin care at the same time or with an interval less than a preset time.

[0094] Once the cold therapy mode input signal is received, the control module 103 controls the cooling module 101 and the irradiation module 102 to perform skin care simultaneously or at intervals less than a preset time. In the cold therapy mode, the cooling module 101 and the irradiation module 102 work closely together to provide effective care for the treatment area.

[0095] The control module 103 can control the cooling module 101 and the irradiation module 102 to work within an interval less than a preset time, thereby realizing the coordinated work of the cooling module 101 and the irradiation module 102, realizing the user's selection of different working modes and efficient coordination between the modules of the device.

[0096] As an embodiment, operating within an interval less than the preset time can mean that the cooling module 101 and the irradiation module 102 operate simultaneously. This simultaneous operation of the cooling module 101 and the irradiation module 102 maximizes the synergistic effect of cold therapy and light therapy. The cooling module 101 reduces the temperature of the treated area, alleviating inflammation and reducing redness and swelling, while the specific wavelength of light output by the irradiation module 102 can sterilize, reduce inflammation, and promote collagen production. The simultaneous operation of these two modules can enhance the effectiveness and efficiency of treatment.

[0097] After determining that the skin care device executes the light-heat coordinated mode or the multi-stage mode, the control module 103 controls the cooling module and the irradiation module to perform skin care.

[0098] It should be noted that the skin care device may include multiple working modes, and the multiple working modes may include a cold therapy mode, a photothermal synergy mode and a multi-stage mode.

[0099] The cold therapy mode may be a mode in which the control module 103 controls the refrigeration module 101 and the irradiation module 102 to work simultaneously, so as to provide cold therapy care to the care area.

[0100] Photothermal synergy mode means that the skin care device 100 uses both electrical and optical signals to synergistically heat the treatment area. In this mode, the electrical signal can penetrate deep into the subcutaneous tissue of the treatment area to heat it, while the optical signal can heat the skin surface in the treatment area, thus achieving photothermal synergistic heating of the treatment area.

[0101] The multi-stage mode can be a mode for performing care in stages. In this mode, the skin care device 100 can activate tapping of the care area with an electric signal according to a preset frequency band, and can also cycle through the frequency bands for activating tapping of the care area, thereby achieving multi-stage care of the care area.

[0102] The skin care device 100 can also start the cold therapy mode to perform cold therapy on the care area after running the photothermal synergistic mode and / or multi-stage mode. The cold therapy mode after the photothermal synergistic mode and / or multi-stage mode can be used to alleviate the irritation to the skin during the photothermal synergistic mode and / or multi-stage mode care process.

[0103] As an embodiment, the blue light emitting module or the green light emitting module includes a light emitting element, and the light emitting element includes at least one of a semiconductor light emitting diode, a laser diode, a fluorescent material, and an organic light emitting diode.
